ADHD is the most common pediatric neurobiological condition affecting approximately five percent of the pediatric population (Faraone, Stephen V., Sergeant, J. et al. 2003; Feldman & Belanger 2009). ASD is being increasingly recognized as affecting a substantial amount of the pediatric population, with recent prevalence data showing 1 in 68 affected (U.S. Department of Health and Human Services 2010). Prior to the introduction of DSM-5, exclusion criteria precluded the diagnosis for ADHD when ASD was present (American Psychiatric Association 2013). Studies have shown that 41%-71% of children with ASD also meet criteria for ADHD, meaning up to 1% of the population may have comorbid ADHD and ASD (Goldstein & Schewbach 2004).
